4 Claims.

This invention pertains to improvements in engine hoisting devices and is particularly related to a novel work engaging device especially adapted to lifting automotive vehicular engines, particularly of the V-type, into and out of the chassis of the vehicle.

An object of this invention is to provide an improved lifting device or bale adapted to engage an internal combustion engine or the like, especially of the V-type, for lifting it into or out of the automotive vehicle chassis.

Another object of this invention is to provide an improved motor lifting device which may be folded up and compacted for storing in a drawer of a tool box, but which at the same time has ample capacity for engaging and lifting an internal combustion engine from a motor vehicle.

Still another object of this invention is to provide a hinge type work engaging bale or hook operatable in conjunction with a lifting crane for engaging and supporting an internal combustion engine for manipulating the engine into or out of the automotive chassis.

Still another object of this invention is to provide a lifting member for an internal combustion engine which is self-locking and positive and secure in its action in supporting and lifting an internal combustion engine.

Further features and advantages of this invention will appear from a detailed description of the drawing in which:

Fig. 1 is an end elevation of the engine hoisting device shown carrying an internal combustion engine, incorporating the features of this invention.

Fig. 2 is a plan view of the engine hoisting device shown in Fig. 1.

Fig. 3 is an end elevation of the lifting device shown in released position when not supporting an engine.

Fig. 4 is a side elevation of the lifting device shown in Fig. 3.

For exemplary purposes this invention is shown applied to lifting a conventional V-type of internal combustion engine in having the usual cylinder blocks H and I2 and the pan l3. The device incorporating the features of this invention comprises a main suspension member M which is supported by a suitable universal connection at IE to the eyelet ring [6 carried on a suspension cable I! of a conventional hoist, not shown.

The lower end of the suspension member I4 is pivotally mounted on a hinge pin l8 from which is also pivotally mounted the outer work engaging members or blades l9 and 20 which may be preferably hinged around the pin I 8 by means of a usual piano hinge construction in COnjllnCBlUn Wlth suspension member :4 as best seen at 2! inl'ig. 4. A pair of stop members Ma and lib to note that the members i 9 and 20 may be folded up to the positions I91? and 20b, as shown. in Fig. 3, so that when the unit is detached from the eyelet l6 and cable l1, it may be readily stored away in the mechanics tool box drawer without taking up excessive room while at the same time making it readily available for lifting an engine into and out of an automotive chassis.

When in operation, as best seen in Fig. 1, the upward thrust provided by the cable I! is transmitted in the vertical direction indicated by the 28 and 29 of the motor block ID to thus serve as a rigid and positive supporting medium for the engine.

I claim:

1. In a hoisting device, a vertical suspension member, means for connecting the upper end of said member to a lifting cable, a pair of fiat plates forming work engaging blades pivotally mounted along their lower edges for swinging movement in a vertical plain about a common axis on the lower end of said suspension member, means on her, and work engaging abutment ends on the upper edges of said blades located perpendicular to the plane of said blades adapted to engage in parallel contact the surfaces of the object to be lifted.

2. In a hoisting device for an automobile engine, a vertically disposed suspension member, means for supporting the upper end of said member on a lifting crane, a hinge pin carried in the lower end of said suspension member, a pair of work contacting blades pivotally mounted on said hinge pin one on each side of said suspension member about a common axis of said hinge pin, work engaging ends on the outer edges of said blades located at right angles to the plane of said blades adapted to engage in parallel contact the surfaces of an object to be lifted, and stop means on said suspension member to limit downward swinging motion of said blades to a position above a horizontal plain passing through axis of said hinge pin.

3. In an engine hoisting device comprising a pair of hinged work engaging blades, work engaging surfaces on the outer ends of said blades located at right angles to the plane of said blades adapted to engage in parallel contact the surfaces of an engine to be lifted, a hinge pin having a horizontal axis pi' votally interconnecting said blades, a suspension member pivotally mounted between said blades about said hinge pin, means for'universally' supporting said suspension member at its upper end on a hoisting cable of a lifting crane, and stop means for limiting the downward swinging movement of said blades to a position above the horizontal plain passing through the axis of said hinge pin.

4. In an engine hoisting device comprising a pair of hinged work engaging blades, work engag- 4 ing surfaces on the outer ends of said blades located at right angles to the plane of said blades adapted to engage in parallel contact the surfaces of an engine to be lifted, a hinge pin having a horizontal axis pivotally interconnecting said blades, a suspension member pivotally mounted between said blades about said hinge pin, means for universally supporting said suspension memher at its upper end on a hoisting cable of a lifting crane, stop means for limiting the downward swinging movement of said blades to a position above the horizontal plane passing through the axis of said hinge pin, said hinge pin being arranged to allow pivotal swinging of said blades to a juxtaposed position of said blades adjacent to said suspension member to facilitate storage of said lifting device when not in use.
